Thanks for the replies everyone.
Since being diagnosed I have already been following quite a restricted diet. For example, I haven't been eating gassy foods, foods with fiber/roughage, spicy, oily meals. I also stopped drinking caffeine, milk, carbonated drinks, alcohol. I agree that a nutritionist may still be able to offer some insight to structuring a better diet. I've kept a detailed food diary for several months and nothing in particular seems to stand out as a trigger food.
My doctor didn't offer many specific recommendations but said that he has told some of his patients to simply try eating the opposite of what they have been eating - with some success. The two things that came up for me to try first were eggs and fish. Even eating fish seems like a big deal as I don't feel that I should harm another living being for my own purposes - when I was a meat eater I couldn't relate to this rationale but I'm sure some of the vegetarians out there know where I'm coming from.
Yes, I've also read that meat is much harder to digest than veg; but given that so much is unexplainable about
UC, you never know whether some high quality animal protein might offer some relief.
